    yep, few lightning strikes out that way. that area had some of the best heating early on. HRRR has been awful w/ this pattern past few days, looks to be a repeat today.

    the 12z OKX sounding shows a convective temp of only 83F. Won't take much more heating to get showers/storms to pop today. seabreeze fronts will probably bring the first cells of the day to the area early this afternoon.

    PWATs will be over 2" tomorrow and we have this weak upper feature currently over WV moving overhead - the past 2 days this has produced widespread PM storms over the Mid-Atlantic and interior NE. Development has been occurring by late morning, so I think we could see storms off/on throughout the afternoon tomorrow. The frontal feature to our N doesn't move through until late evening.

    legit threat seeing what's out west and knowing that a lot of folks will be bbq'ing or at the beach today.

    getting good pressure falls near and north of the warm front now, which is allowing the bubble high over chicagoland to to weaken and shift northeast over the lake. there is also subsidence behind the earlier convection, which will be replaced w/ lift and fairly widespread convection later in the evening as the LLJ increases. severe weather is possible but i'd think some flash flooding is probably the bigger threat across MO, IA, IL and maybe southern WI overnight.

    Totally agree; 12Z 3km NAM may have the best idea, but nothing has really captured the warm sector staying as far S as it is now. That warm front will be hard to budge w/ the new sfc-based severe storms riding it.

    Deep layered southerly flow out of the tropics should easily produce mid-60s+ dew points, similar to Sunday PM. The ECMWF shows a peak of 69F at DCA Friday afternoon.

    Curious to see what the fake BOS final will be; the FAA reported just over a foot on the field on calls this morning.

    Double digits for SE MA.
